WIRE-STRETCHER.

SPECIFICATION forming part of Letters Patent No. `71 1,651, datedOctober 21, 1902.

Application filed January 15, 1902. Serial No. 89,884. (No/model.)l

To all whom, it may concern.-

Be it known that I, OBEN ANDREW, a citizen of the United States,residing at Town-` send, in the county of Schuyler and State of NewYork, have invented a new and useful Wire-Stretcher, of which Vthefollowing is a specification. l

The invention relatesl to improvements in wire-stretchers.

The object of the present invention is to improve the construction ofwire-stretchers and to provide a simple, inexpensive, and ef# icient oneadapted to be readily applied to a post, building, tre'e, or otheranchor or support and capable of being readily reversed to enable it tobe operated at either side.

A further object of the invention is to provide a device of thischaracter which may be rigidly fixed in position and which will not 2orequire any rearrangement of the parts when it is desired to reverse it.

The invention also has for its object to provide a device of thischaracter which will be capable of stretching various Wires other thanfence-Wires and which will also be adapted for use as a mid-wiretake-up.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated v3o in theaccompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure l is a perspective view of a wire-stretcherconstructed in accordance with this invention. Fig. 2 is a longitudinalsectional view. Fig. 3 is a detail perspective view of the gravity pawlor detent. Fig. a is a detail perspective view of a bearing-frameprovided with an eye for adapting the device to be used as a mid-wire 4otake-up.

Like numerals of reference designate corresponding partsin all thefigures of the drawings.

1 designates a bearing bracket or frame composed of sides 2 and 3 and aback 4, connecting the sides and designed to be provided with a screw 5or other suitable means for securing it to a post or other anchor or forattachingv it to a wire. The screw, which is preferably tapered, asillustrated in Figs. 1 and 2, may be constructed separate from thebearing-bracket and is suitably fixed to the same, or it may be formedintegral therewith. The sides 2 and 3 are provided with bearing-openings6 and 7, receiving a shaft or drum 8, having toothed flanges 9, locatedat the inner faces of thevsides 2 and 3 and adapted to be engaged by agravity detent or pawl l0. The shaft or drum is provided between theiianges with a long slot or opening 9a, adapted to receive an ordinarywire or a strip or ribbon, and the ends of the shaft or drum arearranged in the bearing-openings 6 and 7, and the end 1l, which extendsbeyond the frame or bracket, is squared to receive a crank, wrench, orother tool to enable the shaft or drum to be rotated. The opening 6 isenlarged and is provided with a taperedvinner portion 12, adapted whenthe sides of the frame or bracket are slightly spread to permit theshaft or drum to be swung outward horizontally at an angle to remove it.The tapered portion 12 of the opening 6 is adapted to receive one cornerof the squared portion of the shaft, and it will enable the latter to bereadily introduced into and removed from the bearing-openings of theframe or bracket.

The gravity detent or pawl 20, which is intei-posed between the toothedfianges 9 and the back of the frame or bracket, is composed of engagingside portions having upperv and lower teeth 13 and an intermediateconcave yportion 14. The sides of the detent or pawl are suitablyconnected at the top and bottom and the teeth of the upper and lowerportions of the sides are adapted to mesh with the teeth of the ianges9, whereby the drum or shaft is locked against rotation. The upper andlower engaging portions of the sides of the gravity detent or pawl lOare enlarged to prevent the pawl from droppinghrough the spaces betweenthe back off/the frame or bracket and the tootnedrnanges of `u1@ Shaftor drum. 'lhis'construction of pawl or detent enables the devze to bereadily reversed to bring the projecting polygonal portion 1l oftheshaft or drum at either side, so that the device may be operated ateither side of a fence or post or other support to suit the convenienceof the operator.

Instead of employing a screw, as shown in Figs. 1 and 2, the frame maybe provided with the eye l5 (illustrated in Fig. 4 of the drawings) toadapt the device for use as a midwire take-up. The eye l5 is adapted toreceive one portion of awire, and the other p0rtion is adapted to beconnected to the shaft or drum, which may be rotated to stretch the wires to the desired tension.

It will be seen that the device is exceedingly simple and inexpensive inconstruction, that it is adapted to be readily mounted on a post orother support or on a fence-Wire for use as a mid-Wire take-up, and thatit is capable of being readily reversed to enable it to be operated ateither side of a fence, post, or other support or anchor. It Will alsobe seen that the parts do not require any rearrangement When it isdesired to reverse the shaft or drum and that as the engaging portionsof the pawl or detent are arranged at the ends ofthe drum or the shaftthe latter will be securely held.

What I claim is- A device of the class described comprising a bearingbracket or frame, a shaft or drum journaled in the bearing bracket orframe and provided at opposite sides with toothed annular fianges andthe double gravity detent or pawl interposed between the shaft or drumand the back of the bearing bracket or frame and composed of oppositesides suitably connected and provided With enlarged upper and lowerportions, and reduced intermediate portions, the enlarged portions beingprovided with teeth for engaging the toothed flanges, whereby the deviceis adapted to be reversed, substantially as and for the purposedescribed.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two Witnesses.

OREN ANDRE\V.
